Make nodejs native addon to work with nwjs

Looking for C++ software developer with experience in creating native nodejs addons to make addon written for Node compatible with NWJS. Addon uses ffmpeg library to encode images in h264 video and write it as mp4 file. NWJS have it's own version of ffmpeg which can't encode and write video. So when it's loaded in NWJS video codecs and muxers are unavailable. It is required to make addon use the system version of ffmpeg or make patch for build scripts of NWJS version of ffmpeg to add support for video encoding.
